Red Velvet guested on 'NCT's Night Night' radio show during their 'Peek-a-Boo' promotion on November 22nd. The girls were having their song played through the radio when they were asked to take selfies for the show's Instagram.

Irene had the phone on the table, stood up, leaning against a support. She found her desire angle and had both hands placed against her face for her pose. With a few taps on Wendy's shoulder, the latter immediately went towards the camera button and helped the leader with her selfie.
